93 Octane Tune on Boosted Motor

[80FoxCoupe]

I didn't even think of that. That's a very good reason to increase the crank side. I have seen numerous posts about aftermarket crank pulleys snapping the snout off. It's the ATI pulley that is usually the topic of the conversation.

Regurgitated info by many with no hands on experience. I've seen a twin turbo car, 2 whipple cars and an NA car snap the snout off. With that being said, nobody is worried about those.

I was one of the ones who had a crankshaft failure. Dealer did whipple install, ATI balancer, and OPG/CS. Failure happened at 12,800 miles cruising under 70 mph.

I added a MFP crank support on the aluminator I replaced stock motor with.

I believe many of the failures with ATI are due to improper install as the instructions say to measure and hone to fit. 99% of shops, let alone dealers, aren't doing that.

I will say it wasn't until 2 weeks after installing WOT box and using 2 step at track that failure happened on way back home.

Nice! I'd like to get a flex fuel set up but had been told that they're not compatible with the stock ECU. This must be a new product.



I have the factory crank pulley. 1100 seems high to me, and I'm sure ProCharger would be surprised too! When I did the initial install I only wanted 800whp so I didn't have to immediately upgrade from the RST clutch. I told ProCharger tech support my goal and this is the pulley they said would accomplish around that number for my build. What size crank pulley are you running?

That is fantastic! What’s the chances of this becoming compatible with the 2012 Boss 302 ECU in the future?

Unlikely at this stage. We have set the Tricore platform fairly in stone at this stage. The older PowerPCs are very low demand in comparison and people aren't willing to pay the price for the R&D unfortunately.

Any boost controller can be used to limit your boost without changing pulleys. Also known as a torque booster setup

Interesting. I will look into this. Thanks!

Do yourself a favor and get with a tuner that can utilize PCMTEC to build you a custom multi tune. We finished setting up my buddie's car for canbus flex and am about to set mine up the same way.
You can have tune limit airload based on ethanol percentage so that you maybe get a cap of say 1.5-1.6 airload when on 93, but full load on e80+. This way you can run the smallest pulley all the time and have tune automatically adjust for when you have 93 to keep it safe. Basically, tune will start to close throttle once airload is reached.

For canbus flex you will need a Zeitronix box and ethanol flex fuel sensor.

Does it do the same without the zeitronix if you just throw in your own percentage using user flex?

You can manually lock in the ethanol content and not rely on the canbus flex automated feature.
For example if you had an ethanol flex fuel sensor sending info to an innovate ethanol guage, you can just look at guage % then enter the multi tune via cruise control and manually set your ethanol content using the speedometer and up/down buttons.

So if you had 78% ethanol, you'd just go into cruise menu and arrow up/down to 78 mph and set it.

Dang I wish I had that luxury for my vehicle.

I did find this in my search for something similar. Do you know anyone with any experience with this kit?

My bad, I just took for granted you had a s550 since it's a 6g forum.

I don't have personal experience with the proflex kit. Basically it uses an in line ethanol sensor to monitor ethanol content and then adjust the pulse of fuel injectors to deliver the optimum fuel for ethanol % stoich.

However, it does not control ignition timing or any other parameters to my knowledge.

Basically, it will help you run an optimal air/fuel ratio which may help increase power slightly.

Seems to me proflex is more of a convenience item for those who may not want to manually test the ethanol percentage from the pump and then flash tune for optimum stoich.

You can control boost from 0 up to your pulley limit. So if you’re pulleyed at 20 you can use a boost controller and and set it anywhere from 0-20. If you set it at 10 it will come up to 10 just like it normally does and level off and stay there all the way to redline

Does it do the same without the zeitronix if you just throw in your own percentage using user flex?

Correct. It works identically without the zeitronix, you simply enter the ethanol content manually via the +/- buttons. This is what we refer to as "User Flex" in the training videos.

Sorry. Is there a more appropriate place for me to post this thread? (Newbie Mistake)

Yes, you're correct. I spoke with Gray from Advanced Fuel Dynamics and it doesn't adjust timing. He says that I tune the car for 93 and then this system will allow anything from 93 to race fuel to be run through the vehicle.

It would certainly be convenient since the quality of E85 isn't consistent from the pump. I wonder how much power would be left on the table by going this route as opposed to a dedicated E85 tune.

My car is a street car which I drive on a regular basis, so I don't feed it the good stuff at $15 a gallon. I wouldn't be distraught if I left a few ponies on the table, but a few hundred would have me aching. LOL
